Here's the solution ~

Let's use Angle sum property of a triangle :

`\qquad \sf  \dashrightarrow \: 5x - 60\degree + 2x + 40\degree + 3x - 80 \degree= 180 \degree`

`\qquad \sf  \dashrightarrow \: 5x + 2x + 3x - 60\degree + 40\degree - 80\degree = 180 \degree`

`\qquad \sf  \dashrightarrow \: 10x - 100\degree = 180\degree`

`\qquad \sf  \dashrightarrow \: 10x = 180\degree + 100\degree`

`\qquad \sf  \dashrightarrow \: 10x = 280\degree`

`\qquad \sf  \dashrightarrow \: x = 280\degree / 10`

`\qquad \sf  \dashrightarrow \: x = 28\degree`

The value of x is 28°
